1 Claim. (Cl. 13165) This invention relates to improvements in cigarette making machines, and particularly to those machines which are operated by hand.

An object of the invention is to provide a simple, compact and durable machine that will produce cigarettes of the desired size and length.

Other objects will be set forth hereinafter.

The device consists briefly in means to feed tobacco to a strip of paper carried by an endless belt through a shaper or former, to form a cigarette tube by overlapping the edges of the strip over the tobacco charge and crimping them together, and to out 01f the tube in suitable lengths. The device is operated by a hand crank.

Reference is made to the accompanying drawings in which:

Figure 11 is a view of the cutting mechanism.

Figure 12 is a back view of the cutting wheel.

Referring to Fig, 1, the vertical supporting wall I is supported on a suitable base, such as a table. Pins Ill and H journal pulleys 20, 2| of an endless belt 2. A pin |2 journals the paper roll l3. A pin 14 journals a gear wheel 25 and crimping wheel 44. A pin l5 journals the gear wheel 24. A portion of the upper part of the wall I is cut away and has brackets IE to support a feeding tray H. An end plate l8 is secured to the base. The end of the wall has a slot l9 to permit the entrance of gear 5|, to mesh with gear 23. The belt 2 is driven by a gear wheel 23 secured to the pulley 2| on the pin Meshing with the gear wheel 23 is a gear wheel 24 on the pin I5. A pin 23 from the wall I supports a hand crank 28 with a toothed end meshing with gear wheels 24 and 25. The belt 2 has a tension device 22, In the drawing this is shown as actuated by a spring.

The trough 3 is supported at one end on the pin 30 and towards the other end by the bracket 3|, mounted adjustably on the wall I. The front part of the trough 3 is open. It starts flat at the end where the belt 2 and strip of paper from the roll I3 enter. As it advances it becomes bowed downwardly and narrowed, as shown in cross sections Figs. 6 and 7. The sides of the trough 3 in this portion have inturned lips, an inner lip 32 to direct the belt 2 and an outer lip 33 to direct the strip of paper. The rear part of the trough 3 continues the bowed semi-circular form which gradually diminishes in the diameter as shown in cross sections, Figs. 8, 9 and 10. The sides 34 of this portion of the trough 3 extend laterally and then are bent inwardly to receive the lateral edges of the cover 35 which is arched and gradually diminished in diameter to correspond with the trough 3. Transparent material is used for the cover. The cover 35 has a' notch 36 and a slot 31.

Secured within the cover 35 is the insert guide 4, which starts as a full arched semicircle and gradually narrows to its slotted end 40 in the sides of which slot is journalled a minute burr wheel 4|. The wider portion of the guide 4 has secured to its surface a spacer plate 42 which narrows rearwardly. By this means a passage forthe edges of the'belt 2 and the paper is provided between the cover 35 and the insert 4, as shown in Fig. 8. The insert 4 is bent upwardly towards its end 40. A minute bafile 43 extends under the burr wheel 4|, to protect the wheel from the tobacco as it passes.

Mounted on the pin l4 and integral with the gear wheel 25 is the crimping wheel 44 which bears on the burr wheel 4| through the overlapping edges of the paper which it crimps together.

The cutter mechanism is as follows:

A bracket 5 secured to the outside of the wall I by the pin ll supports a pin 50 on which are journalled a gear wheel 5| which meshes at right angles with the gear wheel 23 and a cutter wheel 6.

The gear wheel 5| has a pin 52 projecting from both sides. On the outer side the pin 52 travels in a circular slot 5|] in the wheel 6, beyond which it is connected to a pin 6| near the edge of the wheel 6 by a spring 62. A removable cutting blade 63 is secured tangentially to the wheel 6. The edge of the wheel 6 is cut away as shown to provide a stop 64,

Joumalled on the bracket 5 at its outer end is a cam 53 held under tension by the spring 54 to meet the pin 52 on the inside of the gear wheel The cam 53 has a projecting tooth 55 which bears on the edge of the wheel 6 and enters the stop 64 where it remains until the cam 53 is moved outwardly by the pin 52 and releases the wheel 6.

A bracket 1 secured to the base carries a short tube Hlto receive the cigarette tubefrom the belt'2. The end plate l3 has a similar short tube I8 mounted to provide a narrow opening through which the blade 63 passes to cut off the cigarette tube.

With a construction such as above .set .forth, or its equivalent, the operation is as follows:

The strip of paper from the roll I3 is fed over the belt 2 into the trough 3 and below the outer lips 33. The belt 2 carries the paper past the tray I! from which the tobacco is fed into the trough 3 in a suitable amount. The paper bearing its charge of tobacco then passes under the insert '4, as shown in Fig. 8, the edges of the paper being gradually brought together and then overlapping, one edge being lowered by a notch 36 in the cover 35. The tobacco is now below the insert 4, the overlapping paper passing above the insert and between the burr wheel 4| on the end of the insert 4, and the crimping wheel 44 operating through the slot 31 in the cover 35. The tobacco passes under the bafile 43 free from the burr wheel 4|. As the formed cigarette leaves the cover 35 and the insert 4 it provides a continuous tube which is carried by the belt 2 and through the tubes and [8 The blades 63 operating under tension cuts the cigarette tube in the proper lengths and the operation is completed.

The operation of the cutter mechanism is as follows:

The gear wheel 5| is rotated by the gear wheel 23. As it rotates the pin'52 in the'slot '60 held by the spring 62 and pin 6| .rotatesthe wheel 6. When the tooth 54 of the cam 53enters the stop 64 it holds the wheel 6 from rotation and the pin 52 travels in the slot 60 and extends the spring 62. As the cam 53 meets the .pin 52 on the .gear wheel 5| the tooth 54 is moved out of thestop 64 and the wheel 6 is released and due .to the tension of the spring 62 the wheel 6 snapsround rapidly. The blade 63 passing between the tubes 10 and I3 makes a clear out of the cigarette tube.

An important feature of this device is the transparent cover 35 over the forming portion of the trough 3. It is slidably mounted in the overlapping edges 34 of the trough 3 and can be readily removed. By means of this cover 35 the forming operation can be observed and any defeet in the forming operation detected and readily corrected.

By means of the adjustable bracket 3| the pressure between the crimping wheel 44 and the burr wheel 4| can be regulated.

It is to be noted that due to the shape of the insert the tobacco is maintained in cylindrical form and .the cigarette produced is not flattened as in many cigarette machines which employ a grooved roller on the tobacco before the paper overlaps the charge.

It is to be further noted that due to the mounting of the feeding, forming and driving :mechanism on one side .of a vertical wall, all these partstare open and readilyavailable to the control and observation of the operator.

What we claim is:

In a cigarette machine the combination of a vertical wall, an endless belt mounted on pins inithe wall, a trough supporting the upper layer of the belt, a feed portion of the trough open above, a horizontal tray mounted on the wall, its edge overlapping one edge of the trough, a forming portion of the troughhavingan arched cover secured to the sides of the trough,.an arched insert secured'to one end ofthe coverand spaced apart therefrom, a burr Wheel 'joumalled in the narrowed far end of the insert, a'crimping Wheel bearing on the burr wheelthrough a slot in the c0ver,;gear wheels journalled on :pins in .the wall adapted to rotate the crimping wheel and drive the belt, :a .hand crank "meshing with the gear wheels, means .for rsupporting a 'roll of "paper mounted to feed a strip of paper on the :belt, and means for cutting said paper periodically, the insert having an upward bend towards the burr wheel end adapted 2130 provide spring tension to the burr wheel against the crimping wheel.
